水泵叶轮是水泵的核心部件,如果使用不当,常会损坏叶片(杂物进入泵体打坏叶片或进水条件恶劣等原因使叶片表面产生汽蚀破坏);如果水泵实际工作扬程与额定扬程相差悬殊,就会形成高能耗、低效率运行。水泵叶轮的好坏及使用是否合理直接关系到泵站装置效率的高低。目前,各地泵站面临的主要问题是,怎样充分利用泵站原有设备及水工建筑进行节能技术改造,从较少的投资换取较大的经济效益。本文就更换水泵叶轮以改造泵站谈几点看法。1.在保证灌排要求的前提下,选用与当地运行条件相适应的泵型叶轮,去更换那些与当地运行条件不相适应的泵型叶轮,以提高水泵的运行效率。为此,我们在天平乡新联机电排灌站做
Pump impeller is the core components of the pump, if used improperly, often damage the blades (debris into the pump body to damage the blade or bad water conditions such as vane erosion caused by vandalism); if the actual working lift and rated head difference , It will form a high energy consumption, low efficiency operation. Pump impeller is good or bad and the use of reasonable or not directly related to the level of pumping station efficiency. At present, pumping stations around the main problems facing is how to make full use of existing pumping station equipment and hydraulic construction of energy-saving technological transformation from less investment in exchange for greater economic benefits. This article on the replacement of the pump impeller to transform the pump to talk about several points. 1. Under the premise of ensuring irrigation and drainage requirements, select the pump impeller compatible with the local operating conditions to replace the pump impeller that is incompatible with the local operating conditions to improve the operating efficiency of the pump. To this end, we are in Tianping Township, the new line Drainage and Irrigation Station to do
